MOISTUREPROOF CONTAINER.

Application med April 1a, 1919. serial No. 290,928.

To all whom it may concern.' I Be it known that I, FREDERICK P. l/Voon, a citizen of the United States, residing in New York, in the county of New York and 5 State of New York, have invented a newl and useful Improvement in Moi-stureproof Containers, of which the following 1s a specification.

This invention relates in general to mois-v Fig. 2 Vis a vertical partial section therel through, and

Fig. 3 is an enlarged detailed similar view. Y Upon the drawing l have` shown a can body wall of fibrous materiali and composed 41of an internal carcass 11 Consisting of vtwo vlayers of fiber board or paper 12 connected together by any suitable cement, glue being sufficient, although fusible cement maybe used if desired. Another' ibrous'layer 14 is provided upon the outside of the body and is cemented thereto by an interposed layer 15 of fused cement, asphaltum being well Y adapted for 'the purpose. The cover inthe lpresent instance consists of ,a metal body or sheet 16 pressed outwardly at 17 to form a shoulderj18tting within thetop of the body. Beyond the shoulder 18, the cover extends outwardly at 19 over the end wall f of the body and thence downwardly at 2O in acylindrical ange adapted to 11e against 4,5 the Outer face of the body. The edge 21 of the flange V20 is left as it is formed by' the punching or press work in constructing the body and is bent inward slightly at 22 and forced to cut or Otherwise enter through the outer liber layer 14 and to extend into 50 or at least intocontact with the' layer of fused cement l5.

The fused cement forms an absolutely moisture proof layer in the body and the tin or other sheet metal cover is also of vcourse Ymoisture proof. rlhe contacting of the two therefore produces a complete en- Casement of the contents within the can and alsoy of the inner fiber layer or carcass 11 so that there is no chance for moistureto 6i@ enter into the can. i e

Itis thought that the invention and many of its attendant advantages will be under- Vstood from the foregoing description, and

it will be apparent that various'changes may 6&5 be made in the form, construction'and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

l claim 1 vA moisture-proof container formed of a l laminated paper body and having metal ends, laminations of said body being con- 7S neeted together by a continuous film of non ,porous fused cement -and the said metal end's p having shoulders arranged within the ends of the laminated body from whichthe metal extends up andover to the outside thereof, the edges of said ends being forced through the outer liber lamination and into contact with the said film of cement, whereby said ends are joined to said film with impervious connections the whole forming a package comprising a continuous impervious enclosure of cementand metal.
